Towing your vehicle behind your RV is a great way to experience more of the adventure on your cross-country excursions. Whether you're towing a compact car or a full-size truck, CURT has the perfect solution to help you Bring It! CURT towed-vehicle RV harnesses are a vehicle-specific, plug-and-play solution to wiring your vehicle for dinghy towing. They use original-equipment-compatible connectors to plug into your vehicle's wiring system without any cutting, splicing or soldering required.
They provide a standard 4-way flat connector to plug into the RV socket and synchronize the vehicle's tail lights, turn signals and brake lights with the RV's. Because each towed-vehicle RV harness has a vehicle-specific design, installation is fast and easy. This particular RV dinghy towing wiring harness is designed for specific years of the Ford F-150.
CURT RV harnesses are also built to provide long-lasting operation. They feature integrated block diodes that protect the vehicle's circuits from the RV signals. They isolate the sensitive vehicle electronics, keeping them from overheating and short circuiting. Every CURT towed-vehicle RV harness comes ready to install with all necessary hardware included. They also come with a 4-way flat extension to provide plenty of length to plug into the RV socket, as well as a connector mounting bracket to mount the connector on the vehicle.

Yes, the CURT Custom Towed-Vehicle RV Harness, Select Ford F-150 52110 (Part #BKDK52110) is designed to fit the 2021-2026 Ford F-150.
The CURT Custom Towed-Vehicle RV Harness, Select Ford F-150 52110 (Part #BKDK52110) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
Part 52110 is a custom wiring harness manufactured by Curt Manufacturing designed to connect RV/Motorcoach towing equipment to trucks. It uses a 4-flat connector and is installed in the driver-side engine bay to provide the electrical connection needed for towing.
The manual does not specify which truck makes, models, years, or cab/bed configurations are compatible with part 52110. Contact Curt Manufacturing or consult a fitment database with your vehicle's year, make, model, and cab style to confirm compatibility before purchase.
You need a wire cutter. The manual lists this as the only required tool. Proper tools will improve installation quality and reduce installation time.
The manual does not specify whether cable ties are included. You will need cable ties to secure the wiring harness away from hot or moving parts in the engine bay during installation, so confirm availability before beginning.
The manual does not specify whether battery disconnection is required. However, the warning advises not laying tools across the positive terminal to avoid ground shorts, sparks, and electrical shock. Consult the vehicle manufacturer's service manual or contact Curt Manufacturing to confirm whether battery disconnection is necessary for your specific vehicle.
The factory connector is located in the opening above the front driver-side wheel well, between the air filter, the driver-side front fender, and the firewall. It is a black connector that you will disconnect and then install the custom 52110 wiring harness between the factory wiring.
Route the 4-flat wire along the driver-side inner fender to the front of the vehicle and mount it in a convenient location for connecting to the RV/Motorcoach. Use cable ties to secure the wiring harness away from hot or moving parts in the engine bay to prevent damage.
Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower. The manual does not specify the exact product rating in amperes or watts. Contact Curt Manufacturing or check the product documentation for the specific lamp load rating of part 52110.
Do not lay tools across the positive terminal (typically marked with red covers or a red '+' symbol). Doing so can cause a ground short, resulting in sparks and/or electrical shock. Keep tools clear of the positive terminal during installation.
Periodic inspection of all wires and connections should be performed to ensure there is no visible damage or loose connections. The manual does not specify the exact inspection interval. Perform visual checks regularly, especially before towing, and after any incident or exposure to moisture.
Test for proper function by using a test light or by connecting a properly wired trailer to the 4-flat connector. The manual does not provide detailed testing procedures beyond these two methods. Ensure all connections are secure before testing.
The manual does not list specific vehicle compatibility. Check with Curt Manufacturing or a fitment database using your vehicle's year, make, model, and cab style.
A wire cutter is the only tool listed as required. Cable ties are needed to secure the harness but the manual does not confirm if they are included.
No drilling is mentioned in the installation steps. The harness connects to an existing factory connector in the driver-side engine bay and is routed along the inner fender using cable ties.
Do not lay tools across the positive terminal (red covers or '+' symbol) to avoid ground shorts, sparks, and electrical shock. Do not exceed the product rating or tow vehicle lamp load rating, whichever is lower.
Perform periodic inspection of all wires and connections to check for visible damage or loose connections. The manual does not specify an inspection interval.
